PASSENGER-SIDE AIR BAG MODULE [STANDARD DEPLOYMENT CONTROL SYSTEM]
Purpose
-
When the passenger-side air bag module receives an impact from a frontal or frontal offset collision, the operation (deployment) of the air bag mediates the impact to the head and face of the passenger.
Function
-
When the passenger-side air bag module receives an impact from a frontal or frontal offset collision, the air bag is operated (deployed) by the operation signal sent from the SAS control module.
Construction
-
The passenger-side air bag module is located in the dashboard.
-
The passenger-side air bag module consists of the inflator and air bag.
-
The inflator consists of the igniter, ignition agent, gas-generating agent and the filter.
Operation
-
The passenger-side air bag module operates (deploys) the air bag by activating the internal inflator.
-
The inflator operates (deploys) in the following order:
-
When an operation (deployment) signal is received from the SAS control module, the igniter built into the inflator generates heat and ignites the ignition agent.
-
The ignition of the ignition agent causes the combustion of a gas generating agent which forms nitrogen gas.
-
The nitrogen gas is cooled at the filter and the filtrate is injected into the air bag.
Fail-safe
-
